og 156

Dirt roads may evoke the bucolic simplicity of another century, but financially strained townships point out that dirt roads cost twice as much as maintaining paved roads.

(A)  dirt roads cost twice as much as maintaining paved roads

(B)  dirt roads cost twice as much to maintain as paved roads do

(C)  maintaining dirt roads costs twice as much as paved roads do

(D)  maintaining dirt roads costs twice as much as it does for paved roads

(E)   to maintain dirt roads costs twice as much as for paved roads

正确答案中as much as的用法好怪哦，哪位高手讲解一下？？

关于选项D，OG11说不并行，没有异议。但og还说It has no referent. 我觉得it应该可以指代maintaining，有什么问题吗？

请指点，谢谢！

翻出一个老贴

我也很想知道为什么D中的it不能指代maintaining...

"it" represent maintaining the road , i think

是不是类似于比较结构中的that或those,所以即使指代maintaining the road,也应该用that而不是it.
